Description

Die Erfindung betrifft die Verwendung von insbesondere homopolymeren Cycloglycanen mit einer ringförmigen Grundstruktur aus 2 bis 40 Monosacchariden im Ring zur Verhinderung der Invasion und Infektion von Säugerzellen durch Pathogene und zur Bekämpfung von durch derartige Pathogene verursachten Erkrankungen.The invention relates to the use in particular of homopolymeric cycloglycans having a ring-shaped basic structure of 2 to 40 monosaccharides in the ring for preventing the invasion and infection of mammalian cells by pathogens and for controlling diseases caused by such pathogens.

Die US-A-5 221 669 beschreibt antivirale Mittel, welche α-Cyclodextrinsulfates alleine oder zusammen mit bekannten antiviralen Agenzien enthalten. Diese bekannten Mittel sollen zur Hemmung der Infektion des HIV-Virus wirksam sein.The US-A-5 221 669 describes antiviral agents containing α-cyclodextrin sulphates alone or together with known antiviral agents. These known agents are said to be effective in inhibiting the infection of the HIV virus.

Aus der WO 90 00596 A sind ebenfalls Cyclodextrine enthaltende antivirale Mittel zur Bekämpfung des HIV-Virus bekannt.From the WO 90 00596 A For example, cyclodextrin-containing antiviral agents for the control of the HIV virus are also known.

XP002241408 und JP 03 101754B befassen sich mit verzweigten Cyclodextrinen, die als Konservierungsmittel für unter anderem Nahrungsmittel eingesetzt werden.XP002241408 and JP 03 101754B are concerned with branched cyclodextrins, which are used as preservatives for, inter alia, foods.

Die Adhäsion sowohl pathogener Organismen als auch zellschädigender Substanzen an die Oberfläche von Säugerzellen ist der erste Schritt und eine unabdingbare Voraussetzung für eine Infektion bzw. Schädigung der Zelle. Die Interaktion zwischen den Pathogenen und den Zellen kommt durch eine Ligand-Rezeptor-Beziehung zustande. Glycostrukturen spielen bei diesen Beziehungen bzw. Wechselwirkungen eine wichtige Rolle.The adhesion of both pathogenic organisms and cell-damaging substances to the surface of mammalian cells is the first step and an indispensable prerequisite for infection or damage to the cell. The interaction between the pathogens and the cells comes about through a ligand-receptor relationship. Glycostructures play an important role in these relationships or interactions.

Eine Möglichkeit, derartige Ligand-Rezeptor-Beziehungen zu beeinflussen, besteht in der Blockierung und/oder der strukturellen Veränderung der jeweiligen Rezeptoren auf der Zelloberfläche oder der Liganden.One way to affect such ligand-receptor relationships is by blocking and / or structurally altering the respective receptors on the cell surface or ligands.

Verschiedene Kohlenhydratmischungen haben sich in spezifischen Testsystemen als sehr wirksam erwiesen, die Adhäsion beispielsweise von Mikroorganismen an die Zelloberfläche zu vermindern oder ganz zu verhindern, man vergleiche: Kunz, C.; Rudloff, S. Acta Paediatr. 1993, 82, 903-912 . Andere Substanzen wie etwa die Lewis-Strukturen als Kohlenhydrat-Liganden der Selektine (Adhäsionsproteine auf Endothelien und Lymphocyten), modulieren die Interaktion der Lymphocyten mit dem Endothel beispielsweise im Rahmen von Rolling, Homing und der Invasion bei entzündlichen Prozessen ( Norman, K.E.; Anderson, G.P.; Kolb, H.C.; Ley, K.; Ernst, B. Blood 1998, 91, 475-483 ). Eine weitere wichtige physiologische Rolle im Zusammenhang sowohl mit grundlegenden zellulären Funktionen als auch mit spezifischen Funktionen wie Zelladhäsion, Migration, Chemotaxis, Proliferation, Apoptose, Neuritenwachstum erfüllen die Galactose-erkennenden Lektine, die Galectine. ( Cooper DN & Barondes SH, Glycobiology 1999 9 (10) 979-984 ). Für den Nematoden C. elegans konnte gezeigt werden, dass dessen Galectin LEC-1 verschiedene Galactose enthaltende Oligosaccharid-Derivate mit unterschiedlicher Spezifität binden kann. ( Arata Y. Hirabayashi J. Kasai K, JBC, 2001:276, 5, 3068-3077 ). In einem Mäusemodell konnte durch den Einsatz von Galactose spezifischen Lectinen die Letalität einer experimentellen Listeriose verringert werden ( Stoffel B, Beuth J, Pulverer G, Zentralbl. Bakteriol. 1996, 284:439-442 ). Die Adhärenz von Mikroorganismen an Wirtszellen kann aber auch der Auslöser von Signalkaskaden sowohl in den körperfremden pathogenen als auch in den körpereigenen Zellen sein.Various carbohydrate blends have proven to be very effective in specific assay systems to reduce or even increase the adhesion of, for example, microorganisms to the cell surface prevent one from comparing: Kunz, C .; Rudloff, S. Acta Paediatr. 1993, 82, 903-912 , Other substances, such as the Lewis structures as carbohydrate ligands of the selectins (adhesion proteins on endothelia and lymphocytes), modulate the interaction of the lymphocytes with the endothelium, for example in the context of rolling, homing and invasion in inflammatory processes ( Norman, KE; Anderson, GP; Kolb, HC; Ley, K .; Ernst, B. Blood 1998, 91, 475-483 ). Another important physiological role associated with both basic cellular functions and specific functions such as cell adhesion, migration, chemotaxis, proliferation, apoptosis, neurite outgrowth is met by the galactose-recognizing lectins, galectins. ( Cooper DN & Barondes SH, Glycobiology 1999 9 (10) 979-984 ). For the nematode C. elegans it could be shown that its galectin LEC-1 can bind different galactose-containing oligosaccharide derivatives with different specificity. ( Arata Y. Hirabayashi J. Kasai K, JBC, 2001: 276, 5, 3068-3077 ). In a mouse model, the use of galactose-specific lectins reduced the lethality of experimental listeriosis ( Stoffel B, Beuth J, Pulverer G, Zentralbl. Bacteriol. 1996, 284: 439-442 ). However, the adherence of microorganisms to host cells can also be the trigger of signal cascades both in the foreign body pathogenic and in the body's own cells.

Eine andere Möglichkeit besteht darin, auf molekularbiologischer Ebene eine Beeinflussung zellulärer Prozesse zu erreichen. Dies kann dazu führen, dass etwa bei den Säugerzellen Abwehrmechanismen ausgelöst werden oder bei den pathogenen Mikroorganismen die Expression von Virulenzmechanismen (z.B. Abschalten von Virulenzgenen bei Bakterien durch Blockierung zentraler Regulatoren) verringert oder verhindert werden. Auf diese Weise kann die Expression bestimmter Oberflächenstrukturen von pathogenen Listerien, die für die Invasion in Wirtszellen verantwortlich sein, durch bestimmte Kohlenhydrate wie Cellobiose erfolgreich gehemmt werden ( Park SF Kroll RH Mol Microbiol 1993 8:653:661 ; WO-A 94/02586 ).Another possibility is to influence cellular processes at the molecular biological level. This can lead to defense mechanisms being triggered in the mammalian cells, for example, or in the case of the pathogenic microorganisms, the expression of virulence mechanisms (for example shutting down virulence genes in bacteria by blocking central regulators) can be reduced or prevented. In this way, the expression of certain surface structures of pathogenic Listeria, which are responsible for invasion into host cells, can be successfully inhibited by certain carbohydrates such as cellobiose ( Park SF Kroll RH Mol Microbiol 1993 8: 653: 661 ; WO-A 94/02586 ).

Mit anderen Worten, die ringförmige Grundstruktur weist nur Monosaccharide einer Art auf bzw. ist aus denselben Monosacchariden aufgebaut.With further preference the cycloglycans according to the invention are homopolymeric cycloglycans. In other words, the ring-shaped basic structure has only monosaccharides of one kind or is composed of the same monosaccharides.

Der Ring der Cycloglycane ist vorzugsweise aufgebaut aus D-Fructose, D-Mannose, L-Fucose, D-N-Acetylglucosamin, D-N-Acetylgalactosamin, D-Xylose, Sialinsäuren (z. B. N-Acetylneuraminsäure), L-Rhamnose, D-Arabinose, D-Allose, D-Talose, L-Idose, D-Ribose, D-Galacturonsäure, Altrose, D-Galactose und Glucosen. Diese Monosaccharide sind ringförmig miteinander verbunden und stellen den Ring der erfindungsgemäßen, insbesondere homopolymeren Cycloglycane dar.The ring of the cycloglycans is preferably composed of D-fructose, D-mannose, L-fucose, DN-acetylglucosamine, DN-acetylgalactosamine, D-xylose, sialic acids (eg N-acetylneuraminic acid), L-rhamnose, D-arabinose , D-Allose, D-Talose, L-Idose, D-Ribose, D-Galacturonic Acid, Altrose, D-galactose and Glucoses. These monosaccharides are connected together in a ring and represent the ring of the inventive, in particular homopolymeric cycloglycans.

Bei den Cycloglycanen können die glycosidischen Verknüpfungen sowohl im Ring als auch bei den mit dem Ring verknüpften, nachstehend näher beschriebenen Glycanen folgende sein: α1-2, α1-3, α1-4, α1-6, α2-3, α2-6, α2-8, β1-2, β1-3, β1-4, β1-6 und β2-1.In the case of the cycloglycans, the glycosidic linkages in both the ring and the ring-linked glycans, which are described in more detail below, can be: α1-2, α1-3, α1-4, α1-6, α2-3, α2-6, α2-8, β1-2, β1-3, β1-4, β1-6 and β2-1.

Die Bindung der Monosaccharide untereinander ist vorzugsweise α- oder β-glycosidisch. Bevorzugte erfindungsgemäße Cycloglycane sind solche, die 6, 7 oder 8 Glucoseeinheiten im Ring in α-1-4-glycosidischer Verknüpfung aufweisen. Dazu zählen die hier genannten α-, β- und γ-Cyclodextrine und die Derivate davon.The binding of the monosaccharides with one another is preferably α- or β-glycosidic. Preferred cycloglycans according to the invention are those which have 6, 7 or 8 glucose units in the ring in α-1-4-glycosidic linkage. These include the α-, β- and γ-cyclodextrins mentioned herein and the derivatives thereof.

Bei den erfindungsgemäßen Cyclodextrinen kann es sich um underivatisierte Cyclodextrine handeln. Es wird daher davon ausgegangen, ohne an dieser Erklärung gebunden zu sein, dass der ringförmige Aufbau der erfindungsgemäßen Cycloglycane für deren im Rahmen der hier vorliegenden Unterlagen beschriebenen Wirkungen verantwortlich ist.The cyclodextrins according to the invention may be underivatized cyclodextrins. It is therefore assumed, without being bound by this statement, that the cyclic structure of the cycloglycans according to the invention is responsible for their effects described in the context of the present documents.

Die erfindungsgemäßen Cycloglycane können auch - wie gesagt - derivatisiert sein, und zwar durch eine oder mehrere funktionelle Gruppe(n). Die Substitution kann am Ring selbst oder an den freien Hydroxylgruppen der diesen Ring bildenden Monosaccharide vorhanden sein.The cycloglycans according to the invention can also - as stated - be derivatized by one or more functional group (s). The substitution may be on the ring itself or on the free Hydroxyl groups of the ring-forming monosaccharides may be present.

Bevorzugte derivatisierte Cycloglycane sind solche, bei denen eines oder alle der folgenden Merkmale erfüllt sind:

  • i) eine oder mehrere der OH-Gruppen eines oder mehrerer der den Ring bildenden Monosaccharide ist bzw. sind durch eine NH2-, SH-, Phosphat-Sulfat-, Nitrat-, Alkyl-, Hydroxyalkyl- oder Carboxyalkyl-Gruppe ersetzt. Bei den Alkyl-, Carboxyalkyl- und Hydroxyalkyl-Gruppen weist der Alkylrest vorzugsweise 1 bis 6 Kohlenstoffatome auf. Die den Ring bildenden Monosaccharide können somit beispielsweise durch eine oder mehrere Methyl-, Ethyl-, Hydroxyethyl-, Carboxymethyl- und Hydroxypropyl-Gruppen, um nur einige zu nennen, derivatisiert sein.
  • ii) eine oder mehrere der OH-Gruppen sowie der eventuell vorhandenen NH2- und SH-Gruppen der den Ring bildenden Monosaccharide sind in Form von Ethern, Estern, Amiden und Iminen derivatisiert. Bei diesen Derivaten kann es sich beispielsweise um Succinyl-, Acyl- (insbesondere mit 1 bis 25 C-Atomen, weiterhin insbesondere mit 1, 2, 3, 4, 5, oder 6 C-Atomen, z. B. Acetyl-) Methylmalonsäureester-, Phosphoglyceryl- und Phosphocholinyl-Derivate handeln. Zu den Acylderivaten zählen ferner insbesondere solche mit ernährungsphysiologisch wertvollen gesättigten und ungesättigten Fettsäuren mit 12 bis 22 C-Atomen
Preferred derivatized cycloglycans are those in which one or all of the following features are fulfilled:
  • i) one or more of the OH groups of one or more of the ring-forming monosaccharides is or have been replaced by an NH 2 , SH, phosphate sulfate, nitrate, alkyl, hydroxyalkyl or carboxyalkyl group. In the alkyl, carboxyalkyl and hydroxyalkyl groups, the alkyl group preferably has 1 to 6 carbon atoms. Thus, the monosaccharides forming the ring may be derivatized by, for example, one or more methyl, ethyl, hydroxyethyl, carboxymethyl and hydroxypropyl groups, to name but a few.
  • ii) one or more of the OH groups and any NH 2 and SH groups of the ring-forming monosaccharides are derivatized in the form of ethers, esters, amides and imines.

Bei den erfindungsgemäßen Cycloglycanen handelt es sich um bekannte Verbindungen oder sie können nach bekannten Verfahren hergestellt werden. Cycloglycane aus kleinen Ringen (beispielsweise mit nur 2 Monosacchariden im Ring) sind beschrieben in: Armspach D., Gattuso G., Königer R., Stoddart JF Cyclodextrins in: Bioorganic Chemistry: Carbohydrates. (SM Hecht ed.) Oxford Univ. Press New York 1999 .The cycloglycans according to the invention are known compounds or they can be prepared by known processes. Small-ring cycloglycans (for example, with only 2 monosaccharides in the ring) are described in: Armspach D., Gattuso G., King R., Stoddart JF Cyclodextrins in: Bioorganic Chemistry: Carbohydrates. (SM Hecht ed.) Oxford Univ. Press New York 1999 ,

Zu den erfindungsgemäßen Cycloglycanen zählen die Cyclodextrine, bei denen der Ring aus dem Monosaccharid bzw. der Monosaccharideinheit Glucose aufgebaut ist. Sie kommen in natürlicher Weise als α-, β- und γ-Cyclodextrin vor. Diese Cyclodextrine werden bevorzugt erfindungsgemäß eingesetzt. Sie werden enzymatisch aus Stärke durch die Aktivität von Cyclodextrin Glycosyltransferasen (CGTasen), einem mikrobiellen Enzym (z. B. Bacillus macerans), gewonnen. Die Unterscheidung in die drei natürlichen Cyclodextrine basiert auf der Anzahl der beteiligten Glucose-Moleküle. α-Cyclodextrin beinhaltet 6, β-Cyclodextrin beinhaltet 7 und γ-Cyclodextrin beinhaltet 8 Glycopyranoseeinheiten, die jeweils in α-1-4-glycosydischen Bindungen zu einem Ring verknüpft sind. Weitere Cyclodextrine mit größeren Molekülen mit üblicherweise bis zu 10 Monosaccharideinheiten sind beilspielsweise beschrieben in MJ Playne & R. Crittenden, Commercial available oligosaccharides, Bulletin of the IDF 313, 1996, 10-22 . Andere Cycloglycane, bevorzugte β-1-2-verknüpfte Cycloglycane, werden im periplasmatischen Raum verschiedener Bakterien nachgewiesen. Ringförmige Moleküle bestehend aus bis zu 40 Monosaccharideinheiten, die derivatisiert (insbesondere an den freien Hydroxylgruppen) sein können, sind z.B. beschrieben in: man vergleiche Talaga P., Stahl B., Wieruszeski J.-M., Hillenkamp F., Tsuyumu S., Lippens G., Bohin J.-P., Cell associated Glucans of Burkholderia solanacearum and Xanthomonas Campestris pv. Citri: a New Family of Periplasmic Glucans; Journal of Bacteriology 1996, 178, 8, 2263-2271 .The cycloglycans according to the invention include the cyclodextrins in which the ring is composed of the monosaccharide or the monosaccharide unit glucose. They occur naturally as α-, β- and γ-cyclodextrin. These cyclodextrins are preferably used according to the invention. They are obtained enzymatically from starch by the activity of cyclodextrin glycosyltransferases (CGTases), a microbial enzyme (eg Bacillus macerans). The distinction between the three natural cyclodextrins is based on the number of glucose molecules involved. α-cyclodextrin contains 6, β-cyclodextrin contains 7, and γ-cyclodextrin contains 8 glycopyranose units, each linked to a ring in α-1-4 glycosydic bonds. Other cyclodextrins with larger molecules, usually containing up to 10 monosaccharide units, are described by way of example MJ Playne & R. Crittenden, Commercial available oligosaccharides, Bulletin of the IDF 313, 1996, 10-22 , Other cycloglycans, favored β-1-2 linked cycloglycans, are detected in the periplasmic space of various bacteria. Ring-shaped molecules consisting of up to 40 monosaccharide units which may be derivatized (in particular on the free hydroxyl groups) are described, for example, in: compare Talaga P., Stahl B., Wieruszeski J.-M., Hillenkamp F., Tsuyumu S., Lippens G., Bohin J.-P., Cell-associated Glucans of Burkholderia solanacearum and Xanthomonas Campestris pv. Citri: a New Family of Periplasmic Glucans; Journal of Bacteriology 1996, 178, 8, 2263-2271 ,

Die erfindungsgemäßen Cycloglycane können nach geeigneten, bekannten Verfahren chemisch, enzymatisch oder in einer Kopplung beider Technologien hergestellt. Diese erfolgt systematisch aus den Monosaccharidbestandteilen oder durch Modifizierung geeigneter Oligosaccharid-Rohstoffe. Bei den enzymatischen Synthesen werden sowohl Transferasen (Leloir, bzw. nicht-Leloir) als auch Hydrolasen (reverse Hydrolyse bzw. Transglycosylierung) eingesetzt. Die Enzyme können dabei sowohl frei als auch eingebunden (etwa Membranreaktor) oder kovalent an einen Träger (beispielsweise beads, Chromatographiematerial oder Filtrationsmembranen) gebunden sein. Es ist auch möglich, pro- oder eukaryontische Zellen zur Synthese einzusetzen, sofern diese Zellen die geeigneten Enzyme aufweisen. Bezüglich weiterer Einzelheiten der Herstellung der erfindungsgemäßen Cycloglycane wird beispielsweise verwiesen auf Carbohydrates in Chemistry and Biology (Herausgeber Ernst, Hart, Sinay) Wiley VCH-Weinheim 2000 Vol. I-IV ).The cycloglycans according to the invention can be prepared by suitable, known processes chemically, enzymatically or in a coupling of the two technologies. This is done systematically from the monosaccharide components or by modification of suitable oligosaccharide raw materials. In the enzymatic syntheses both transferases (Leloir, or non-Leloir) and hydrolases (reverse hydrolysis or transglycosylation) are used. The enzymes can be both free and incorporated (such as membrane reactor) or covalently attached to a carrier (for example, beads, Chromatography material or filtration membranes). It is also possible to use pro- or eukaryotic cells for synthesis, provided that these cells have the appropriate enzymes. For further details of the preparation of the cycloglycans according to the invention, reference is made, for example, to carbohydrates in Chemistry and Biology (published by Ernst, Hart, Sinay) Wiley VCH-Weinheim 2000 Vol. I-IV ).

Ergänzend wird auf folgendes hingewiesen. Ist das erfindungsgemäße Cycloglycan nur aus 2 Monosacchariden aufgebaut, dann ist es nicht substituiert; vielmehr besteht es nur aus dem Ring aus diesen 2 Monosacchariden.In addition, the following is pointed out. If the cycloglycan according to the invention is composed of only two monosaccharides, then it is not substituted; rather, it consists only of the ring of these 2 monosaccharides.

Es wurde nun überraschend gefunden, dass die erfindungsgemäßen Cycloglycane die Invasion und Infektion von Säugerzellen durch Pathogene zumindest verringern oder sogar verhindern und zur Bekämpfung von durch derartige Pathogene verursachte Erkrankungen eingesetzt werden können. Zu diesen Pathogenen zählen invasive gram-positive und gram-negative, pathogene Bakterien, beispielsweise intrazelluläre Bakterien, insbesondere Listerien, und pathogene Viren, beispielsweise Rotaviren.It has now surprisingly been found that the cycloglycans of the invention can at least reduce or even prevent the invasion and infection of mammalian cells by pathogens and can be used to combat diseases caused by such pathogens. These pathogens include invasive Gram-positive and Gram-negative, pathogenic bacteria, for example intracellular bacteria, in particular Listeria, and pathogenic viruses, for example Rotaviruses.

Es wurde beispielsweise gefunden, dass die erfindungsgemäßen Cycloglycane die Invasion und Infektion von Säugerzellen durch Listerien, insbesondere Listeria monocytogenes verhindern können. Die Ergebnisse der durchgeführten Untersuchungen zeigen deutlich, dass weder der Vorgang der Phagozytose an sich, noch die Replikation der aufgenommenen Listerien gehemmt wird. Als besonders stark inhibitorisch erwies sich unter anderem die erfindungsgemäßen Cyclodextrine.It has been found, for example, that the cycloglycans according to the invention can prevent the invasion and infection of mammalian cells by Listeria, in particular Listeria monocytogenes. The results of the investigations carried out clearly show that neither the process of phagocytosis itself nor the replication of the ingested Listeria is inhibited. Among other things, the cyclodextrins according to the invention proved to be particularly inhibitory.

Insgesamt konnte festgestellt werden, dass die erfindungsgemäßen Cycloglycane eine antiinfektive bzw. inhibitorische Wirkung im Sinne einer Infektion mit Listerien und Salmonellen besitzen. Die erfindungsgemäßen Cycloglycane können die Invasion von Listerien in Makrophagen-Zelllinien verhindern. Da der Infektion einer Zelle häufig eine Adhärenz und eine Invasion der Pathogene vorausgeht, ist eine Übertragbarkeit auf alle Pathogene gegeben, deren Infektion nach diesem Mechanismus der Listerien verläuft. Es sind dies vor allem Salmonellen und E. coli.Overall, it was found that the cycloglycans according to the invention have an anti-infective or inhibitory effect in the sense of an infection with Listeria and Salmonella. The cycloglycans of the invention can prevent the invasion of listeria in macrophage cell lines. Since the infection of a cell is often preceded by adherence and invasion of the pathogens, there is a transferability to all pathogens whose infection proceeds according to this mechanism of Listeria. These are mainly Salmonella and E. coli.

Bisher war von den erfindungsgemäßen Cycloglycanen nur bekannt, dass sie andere Substanzen und Substanzklassen komplexieren können, um deren Löslichkeitsverhalten zu verbessern. Erfindungsgemäß konnte jedoch festgestellt werden, dass die Cycloglycane anti-infektive Eigenschaften besitzen, wodurch diese Verbindungen zur Verhinderung oder Therapie einer Infektion eingesetzt werden können, ohne dass ein Zusatz weiterer Substanzen erforderlich ist. Erforderlichenfalls können natürlich auch weitere Wirksubstanzen zusammen mit den erfindungsgemäßen Cycloglycanen zur Anwendung gelangen.So far, it has only been known of the cycloglycans according to the invention that they can complex other substances and substance classes in order to improve their solubility behavior. According to the invention, however, it has been found that the cycloglycans possess anti-infective properties, which makes it possible to use these compounds for preventing or treating an infection without the need to add further substances. If necessary, of course, further active substances can be used together with the cycloglycans according to the invention.

Die erfindungsgemäßen Cycloglycane können nicht nur als freie bzw. ungebundene Cyclooligosaccharide sondern auch an einen Träger gebunden oder daran immobilisiert, z. B daran adsorbiert, eingesetzt werden. Bei diesem Träger kann es sich um ein Peptid/Protein (beispielsweise BSA), ein Lipid, (Glycolipid, Ceramid), ein Polymer oder ein Biopolymer (beispielsweise Kohlenhydrat-Dendrimer, Polysaccharid, Polyacrylamid) oder jedes andere Aglykon handeln.The cycloglycans according to the invention can not only be bound as free or unbound cyclooligosaccharides but also to a carrier or immobilized thereon, eg. B adsorbed thereon can be used.

Diese Mittel können beispielsweise als Tablette/Sachet formuliert sein. Für die Formulierung derartiger Pharmazeutika können übliche Adjuvantien, Träger, Hilfsmittel Verdünnungsmittel, feucht-haltende Mitteln, Verdickungsmittel, Geschmacksstoffe, Süßungsmittel usw.
